Question

50 circular plates each of radius 7 cm and thickness 1.2 CM are placed one above another to form a solid right circular cylinder find the total surface area and the volume of the cylinder so formed​

Answer 1

Answer:Volume=924 cm³

T.S.A=572 cm²

Step-by-step explanation:

radius of cylinder= 7 cm.

height of cylinder =1.2*50=6 cm

vol=π r² h =(22/7)×7×7×6=22×7×6=924 cm³

TSA=2 π r(r+h) =2×(22/7)×7 (7+6) =2×22×13 =572 cm²
